Firefox blocked your visit to this site because the certificate provided for agents.shohoz.com has been revoked and isn’t trusted anymore.

Error code: SEC_ERROR_REVOKED_CERTIFICATE

My anti-virus reports that 30 to 100 times per day, it blocks firefox.exe attempts to establish a connection relying on an expired certificate to to www.temu.com. Can you please stop your attempts ? Or tell me how to stop them ?

After updating Firefox to a newer version, some websites that previously worked on the older version started displaying **"Page Not Secure"** and **"Page Expired"** errors, preventing them from loading correctly.

WHY ARE YOU SHUTTING DOWN WEBSITES ON WIN.10 AND NOT WIN. 11 EG. SECURE CONNECTION FAILED MAKES ME NOT WANT TO USE FIREFOX ANYMORE . WITH ALL THE ADDED CRAP TO WHAT WAS A VERY STREAMLINED BROWSER

An error occurred during a connection to ezproxy.yu.edu.jo. PR_CONNECT_RESET_ERROR

am trying to log into the indian evisa (indianfrro.gov.in) website to print off an ETA (Electronic Travel Authorisation) and when logging into the site I am getting a warning saying potential security risk ahead

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to indianfrro.gov.in . If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the web site, and there is nothing you can do to resolve it.

If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the web site’s administrator about the problem.

I do not know what to do for the best

Secure Connection Failed An error occurred during a connection to mail.yahoo.com. The OCSP response is not yet valid (contains a date in the future).

Try Again

Hello, thank you for taking the time to read my request. I am a long-time user of Firefox, but recently I have encountered a series of bugs.

1. Initially, I couldn't access GitHub. On the same computer, Edge works fine, but Firefox fails to load the page. Sometimes, the page content loads in Firefox, but the layout is completely messed up, leading me to suspect that CSS files are not loading.

2. I uninstalled Firefox, deleted the profile, and performed a complete reinstallation. This time, I couldn’t even open the Firefox account login page, receiving the error `SSL_ERROR_BAD_MAC_READ`.

3. Following online advice, I set `security.tls.version.max` to 3, but the issue persisted. The error changed to `SSL_ERROR_RX_MALFORMED_SERVER_HELLO`. When checking the certificate, the common name was `n.sni-347-default.ssl.fastly.net`.

4. Suspecting an issue with the system or browser certificates, I deleted all self-signed certificates and self-signed CAs (such as Fiddler and Accesser) from the system, but I still cannot access the site.

Please tell me, how should I go about solving this problem?

您好，感谢您在繁忙之中拨冗阅读我的求助。

我是Firefox的老用户，但最近发生了一系列的bug。 1. 最初是github无法访问。在同一台电脑上，用Edge可正常访问，但Firefox无法访问。Firefox有时页面内容可正常加载，但布局全乱，怀疑是CSS文件未加载。 2. 我卸载Firefox，删除配置文件，完全重装。这次连火狐账号登陆页面都无法打开，提示SSL_ERROR_BAD_MAC_READ。 3. 我按照网上的提示，设置`security.tls.version.max`为3，仍然无法加载，报错变为`SSL_ERROR_RX_MALFORMED_SERVER_HELLO`。查看证书，通用名称为`n.sni-347-default.ssl.fastly.net`。 4. 怀疑系统或者浏览器证书有问题，删除了系统内所有自签名证书与自签名CA（fiddler, Accesser）但仍然无法访。

请问我该如何解决这个问题呢？

I have been having issues where I am unable to access the website: www.loki.ch. This is the web site for a Swiss railway magazine. I have always been able to access it previously, but haven't used it now for a few months. However this week when I've tried, I'm blocked access to it (see the attached screen shots). I do note that since I had previously access the web site, there have been updates to Firefox. However, when trying to use either Edge or Google Chrome, they also block me, but just say that unable to access the web site, nothing mentioned about being "Not Secure" as Firefox does. It's not a web site where you have to log in and/or use passwords. Contacting the magazine by Facebook messenger yields no response from them. Posting the issue on a Facebook group, other users have responded that they can access it (one was from Slovenia and the other in the UK). One mentioned issues from Australia where I am. It's not a dangerous or suspect web site, simply a magazine about Swiss Model Trains. I have tried adjusting settings to exempt it in Settings - no change. Not a anti virus issue. None of the suggestions in the FAQ have exactly the same scenario in the screen shots attached.

Surely there has to be some way to bypass whatever is in Firefox Security preventing me from accessing this web site?

I try to connect to a web site but I get this response:

"Secure Connection Failed An error occurred during a connection to help.wned.org. Cannot communicate securely with peer: no common encryption algorithm(s). Error code: SSL_ERROR_NO_CYPHER_OVERLAP

I've had several days where I see this message and cannot sign in the Daily Mail (which I pay for) because I receive this message ecure Connection Failed

The connection to www.dailymail.co.uk was interrupted while the page was loading.

I cannot find a solution and it doesn't happen every time on the site but several times a week. I have VPN, and enhanced tracking which I've tried turning them off but I get the same reply. I'd like a fairly simple answer if possible since I'm not tech smart but need help to see if I'm doing something wrong. I did submit a complaint the Daily Mail who said the problem's coming from Firefox. Thanks for your help

All of a sudden I am getting loads of SPAM emails and when I try to unsubscribe, I get a Secure Connection Failed error. I have marked them as SPAM but they just keep coming, daily.
